Compared with common Blank plate, it has better performance in roughness and surface quality. And common copper electrode has large consumption, low precision and efficiency when processing tungsten carbide, high carbon steel, hardened tool steel, while tungsten copper has greatly improved the efficiency and accuracy. Tungsten copper not only has good electrical conductivity, high soften temperature, wear and corrosion resistance, long service life and low frequency of electrode correction, but also save the production costs based on improving efficiency.

W90 tungsten copper plate is composed of 90% W and 10% Cu, its density is up to 16.75g/cm3, hardness reaches more than HB260, the bending strength is 1160MPa, the conductivity is 27%IACS and the softening temperature is more than 900℃.

Tungsten copper blank plate is composed of high purity tungsten powder and copper powder, by isostatic pressing, high temperature sintering, melting refined copper infiltration process.

W85 tungsten copper plate is composed of 85% W and 15% Cu, its density reaches(15.90g/cm3), hardness more than HB240, electric conductivity is 38%IACS, softening temperature is ≥900℃, thermal conductivity coefficient is between 180-200 (wm/k) and the coefficient of expansion is 7.0-7.5 (10-6k).
